NELSON TINGLEY, OF SCRANTON, PENNSYLVANIA.

BLAST-PRODUCING APPARATUS FOR FORGES.

SPECIFICATION forming part of Letters Patent No. 655,591, dated August 7, 1900. Application filed November 7, 1899. Serial No. 736,156. (No model.)

To aZZ whom, it may concern.-

Be it known that I, NELSON TINGLEY, a citizen of the United States, residing at Scranton, in the county. of Lackawanna and State of Pennsylvania, have invented new and useful Improvements in Blast-Producing Apparatus for Forges, of which the following is a specification.

My invention relates to a blast-producing apparatus for forges.

The objects of the invention are to provide an improved arrangement of water-motor for actuating a fan, to provide in connection with a casing inclosing the water-motor means for conducting heat from the forge into said casing whereby to prevent the water passing through the pipes to the motor from freezing, and to provide means for actuating the fan by other means than that of the motor and from the shaft on which the fan is journaled.

In addition to the above other objects of the invention relate to certain details of construction and combinations and operations of parts, all of which will more fully hereinafter appear.

lVhat I claim as new will be set forth in the claims at the end of the specification.

I have illustrated my invention in the accompanying drawings, in which-- Figure 1 is a view in sectional elevation of the draft-producing apparatus. Fig. 2 is a sectional plan view through the fan-chamber, the cover of the motor-chamber being re moved to disclose the parts therein. Fig. 3 is a plan view of the water-wheel. Fig. 3 is a sectional view of one of the buckets'of the water-wheel. Fig. 4' is a view in elevation showing my apparatus arranged in operative relation with aforge. Fig. 5 is a detail view of a modification in the manner of conducting the heat from the forge to the casing of the apparatus. Fig. 6 is a detail View of another modification of 'the same. Fig. 7 is a vertical sectional elevation of the upper portion of the shaft supporting the fan and the motor. Fig. 8 is a section through the shaft on the line 8 8 of Fig. 7, and Figs. 9 and 10 are detail views of the nozzle construction.

Referring now to the drawings, the numeral 1 indicates a cylindrical casing inclosing the water-motor and the fan operated thereby. The upper part of this casing is provided with a circular opening, as shown at 2, through which air is drawn in by the fan-blades 3 and discharged through an opening 4 in the side of the casing. The bottom of this casing is also provided with a similar opening 5 for a like purpose, and cast integral with the bottom of the casings and surrounding this opening is a wall 6 of a height approximately onehalf that of the entire casing, thereby providing an annular runway 7 around the bottom of the casing. Extending inwardly from opposite sides of the wall 6 and cast integral therewith are arms 8, which support at their inner ends a bearing 9. Extending through this hearing and journaled therein, preferably by means of ball-bearings, as indicated at 10, is a shaft 11. The lower end of this shaft is supported in a cup-bearing 12, cast integral with the outer end of a curved arm 13, flanged at its opposite end, as shown at 14, whereby it may be secured to the bottom of easing 1 by means of suitable bolts passing through said flanged portion. A ball-bearing or an ordinary washer may be provided in the cup-bearing 12, as indicated at 15. On the lower portion of this shaft a belt-wheel or an ordinary gear-wheel may be secured, as shown at 16. On the upper side of easing 1 an arm 17 is shown similar to the arm 13, said arm in this instance being cast integral with the casing. 1n the outer end of arm 17 is journaled the upper end of shaft 11. A belt or gear wheel 18 is also secured on the upper end of shaft 11.

The numeral 19 indicates a sleeve mounted on shaft 11, between which and said shaft I provide ball-bearings 20. The upper end of bearing 8 is recessed to receive a washer 21, between which and the bottom of sleeve 19 I provide ball-bearings 22.

The numeral 23 indicates the hub of the fan, which hub is secured on the sleeve 19 to revolve therewith by means of a set-screw 24. Extending outward fromsaid hub are arms 25, to which the blades 3 are secured. I

The numeral 26 indicates the hub of the water wheel or motor, which is mounted on the lower end of sleeve 19 and secured thereon to turn therewith by means of a set-screw 27. Extending outward from this hub are arms 28, which support at their outer ends an annular rim or flange 29, which projects down--- ward in the runway 7 below the upper edge of the wall 6. Projecting outward from the annular flange or rim 29 are a series of arms 30, on the outer end of each of which arms is provided a bucket 31. As shown in Fig. 3, these buckets are conical in shape and are provided about midwayof their length with an outwardly-curved bottom 32, the purpose of which construction will presently appear.

Extending upwardly through the bottom of easing 1 is a series of pipes 33, each having on its end within the casing 1 a nozzle 34. Each of these nozzles is in the form of a gooseneck-that is, from its base or point of connection with the pipe 33 it is curved upwardly and outwardly toward the wall of casing 1 and then inward for-a short distance toward the center of the casing, this outer curvedend being provided with a suitable mouth piece 35 for forming a jet of water, which mouthpiece lies in the same horizontal plane as the buckets 31, so that the water discharged therefrom will strike on the interior of each bucket in succession. As many of these nozzles 34 may be provided as found practicable. I have indicated three such in the drawings. The purpose had in view of curving the nozzles 34 in the mannerjust described is to provide for the use of a waterwheel of the maximum size. In oaseasmaller size of wheel is desired for any reason I provide a short pipe-section 36 for each nozzle. In using this the mouthpiece 35 is removed from the nozzle and secured in one end of the pipe-section, the opposite end of the latter being then secured in the discharge end of the nozzle. The curve of the bottoms of the buckets 31 is such that as these buckets pass into the line of the jet of water issuing from a nozzle 34 the jet of water will strike these bottoms at a right angle and not in a slanting direction, so that all the force possible is obtained from the impact of the water on these bottoms. In the further movement of the bucket the jet of water will next strike against the side thereof and further add to its momentum. The water passing through the pipes 33 is supposed to come from a source of supply located at such an altitude as that it will cause the water to issue from the nozzles 34 with considerable force. The jets of water thus issuing from these nozzles and striking the buckets 31 in succession will cause the rim 29 to be rotated very rapidly, which in turn, through the connections described, will cause a similar rotation of sleeve 19, and thereby cause the fan-blades 3 to be rotated. As the fan revolves it draws in air through the openings 2 and 5 and discharges it through the opening 4, from which a blast-pipe 37 leads to the forge 38, as clearly shown in Fig. 4. The hub 26, arms 28, rim 29, arms 30, projecting therefrom, and buckets 31 comprise the water wheel or motor.

The numeral 39 indicates a waste-pipe leading from the runway 7. In order to direct the water into this pipe, I provide on the bottom of the runway a ridge 40, extending from one edge of the wall 6 on an incline to the edge of the opening leading to the pipe 39. As the water courses around the runway it will come in contact with this ledge and be directed into the escape-pipe 39.

In order to prevent the water splashing over the rim 29, I provide a plate 41, which is in the form of an annulus and is adapted to extend around the upper side of the runway 7. This annular plate is supported on a ledge or offset 42, formed in the outer wall of the casing 1, and around its inner edge is provided with two depending flanges 43 44, which are adapted to project about the upper edge of the rim 29. In addition to this plate I may also provide a sheet-metal cover 45, which is adapted to be secured within the upper portion of the runway 7 and will operate as a further means of preventing the water from escaping over the rim 29 to the bearings.

In order to prevent the water delivered to the motor from freezing, I inclose the lower portion of the casing 1 below the fan and the portion of the pipes and 39 above the ground in a sheet-metal casing 46. Communicating with the interior of this casing is a pipe 47, which is adapted to convey the heat from the forge to the interior of the casing 46, and thus maintain a degree of heat therein that will prevent the water from freezing. I have illustrated in Fig. 4 one arrangement of this pipe. In this construction the forge is supposed to be provided with a chimney 48, and extending at right angles to this chimney is a fine 49, communicating with the pipe 47. It will be seen that the smoke from the forge can pass directly up the chimney 48, while a suflicient amount of the heat will pass through the fine 49 and pipe 47 into the cas ing 46. In case the forge is not provided with a chimney I can employ either of the constructions shown, respectively, in Figs. 5 and 6. In the first-named figure the fine 49 is shown to be provided with an enlarged opening the mouth of which is vertically disposed and located above the forge, thus allowing the smoke from the forge to pass up ward and a certain amount of the heat to pass into the flue 49, as previously described, or in place of this construction the fine 49 may be given a downward extension 50 and provided with an inclined opening 51, the lower edge of which extends downward into the fire of the forge at one side thereof, so that the smoke and gases will pass up on the outside of the pipe 50, while the heat can pass into the opening 51 and through the flue 49 and pipe 47 to the casing 46. The said casing 46 is provided with a door 52, by means of which a lamp or other heatproducing device may be inserted in the casing, so as to preliminarily heat the same before the apparatus has started in operation. The escapepipe from the casing 46 is indicated by the IIO numeral 53, and this pipe, if desired, may

extend above the casing 46 and then downwardly into the opening 2, as shown in Fig. 4, so that the warmed air of the casing may be again supplied to the fan.

The shaft 11, instead of being rotated by means of the water-wheel, may be rotated through the medium of either the gear 16 or pulley 18, and to this end I provide in the space between the sleeve 19 and the shaft 10 a cam-groove 54, having located therein a ball 55, this arrangement operating in the well-known manner-that is to say, when the fan is propelled by the water-motor the ball 55 will rest in the larger end of the groove 54 and the shaft 11 will not be rotated. When the shaft is propelled, however, from either one of the pulleys 16 or 18, the ball will passto the smaller end of the cam-groove, and thereby cause the sleeve 19 to be rotated with it.

The construction above described will serve to furnish the blast for the forge in a reliable and economical manner, dispensing with the ordinary bellows and with the extra help or extra labor necessary to work the same. i It will be seen that the parts described are simple in construction and that there are no parts to get out of order. At the same time by directing the heat from the forge into the casing of the motor I secure the further advantage that the fan may be operated by waterpower in cold weather without the liability of the water freezing. At the same time if it should be found impracticable to employ the water-motor for any reason the fan may be propelled by means of the pulleys 16 or 18 by any suitable power.
